My best attempt at matching Andy Timmons’ default patch on the Keely Halo pedal.

At heart it is a 375ms delay going into a 500ms delay with some other magics. Obviously you can do this with an H90 using two delays but I forced myself down to just one so you’d have the second algorithm open.

Currently, the only single algorithm on the H90 that allows for a serial delay setup is the HeadSpace, which is a Binson-style delay.

I created this side by side with the Keely pedal so it is close and for sure has the same vibe.

The benefit of the HeadSpace algorithm is you can use the fun BoilTime or Break Time values, which I assigned to the A button.

I didn’t assign any expression options but obvious targets would be Mix, Rec Drive, Feedback, or Wow & Flutter.
